PEDAL EXTENSION.

Specification of Letters Patent.

Patented July 13,1920.

Applioationfiled December 17, 1917. Serial No. 207,534.

To (ZZZ whom. it may concern Be it known that I, FRANK Lnsrnn VVIL-LIAMS, a citizen of the United States of America, residing at Detroit,in the county of lVayne and State of Michigan, have invented certain newand useful Improvements in Pedal Extensions, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to an extension for foot pedals and has specialreference to a foot pedal attachment that can be advanta geously used inconnection with the control pedals or treadles of automobiles and otherself propelled vehicles.

The object of my invention is to provide a simple, durable andinexpensive pedal attachment that may be easily and quickly installed,so that a person may conveniently actuate the control pedal to which theextension is attached, said extension being designed to permit of ashort or long limb properly operating the control pedal or treadle.

The pedal extension is of extremely light weight so as not tooverbalance the pedal or treadle to which it is attached and thedetailed construction of the extension will be hereinafter specificallydescribed and then claimed.

Reference will now be had to the drawings, wherein there is illustrateda preferred embodiment of my invention, and it is to be understood thatthe structural elements are susceptible to such variations andmodifications as fall within the scope of the appended claims.

In the drawing,

Figure l is a side elevation extension Fig. 2 is a cross sectional same;and

Fig. 3 is a perspective view of the extension as attached to theordinary control pedal.

The pedal attachment comprises a substantially Y-shaped plate, havingparallel arms 1 and a depending lug 2. At the juncture of the arms 1 andthe lug 2 there is a boss 3 provided with an opening l having the wallsthereof screwthreaded.

The upper ends of the arms 1 are provided with lateral extensions 5 anddepending gripping members or arms 6, said gripping members or armsbeing disposed of the pedal view of the tion and a portion of set screw7 and this set screw is adapted to cooperate with gripping members orarms 6 in locking the (shaped plate on the head 8 of a control pedal ortreadle 9. The Y- shaped plate is fitted edge of the head 8 on the'front side gripping members so that the arms 1 will be of the head 8and the or arms 6 on the rear side thereof, and by tightening the setscrew 7 against the front face of the head 8, the gripping members orarmsfi will be drawn into snug engagement with the rear face of the head8 to firml Y hold the Y shaped plate in )0sition.

crewed into the opening 4: of the boss 3 is the inner exteriorlyscrewthreaded' end of a post 10, and the outer end of the post isexteriorly screwthreaded so that the socket ll of a tread piece 12 maybe screwed onto the post. The tread piece 12 is somewhat similar to thehead 8 of the pedal or treadle 9, and the length of the post 10determines the space between the tread piece 12 and the head 8 of thepedal or treadle. By using a post of desired length the tread piece 12may be placed a certain distance from the head 8 and maintained inparallelism therewith so that the tread piece 12 may be used in lieu ofthe head 8 to actuate the pedal or treadle 9.

The Y shaped plate and the tread piece may be made of aluminum, and thisis also true of the post 10, although it is preferable to make the postof brass or more indurate metal than the tread piece 12 so that therewill be no danger of the post bending or breaking when pressure isbrought to bear on the tread piece 12 to depress or actuate the pedal ortreadle 9.

What I claim is 1. A pedal attachment comprising a member recessed toprovide walls overlying the opposite faces of a normal pedal with thewalls joined to form a stop formation to limit the movement of themember into position, said member being slotted throughout the length ofone wall, the stop formathe opposite wall, a pedal extension secured toand projecting from said latter wall adjacent to and in alinement withthe inner end of the slot to locate the extension on a non-slottedportion down over the upper of the member, the extension carrying a andadapted to engage the upper face of the pedal face adapted to extend inapproXinormal pedal, and an extension carried by mate parallelism Withthe normal pedal theupper Wall and projecting therefrom at a face, saidmember carrying a threaded elepoint intermediate the stop formation and5 ment adapted .to engage the face of the norsaid element, saidextension carrying a mal pedal, said extension being positioned pedalface extending in approximately parintermediate said element and theslot. allelism with the normal pedal face and 2.
